!Hubzilla Support Forum Hi all,I wrote a post on Wednesday, and then I wrote two comments. Above those comments, there's a yellow line that says "Still trying to send to some recipient channels." So I looked at the delivery report for the comments, and it said "comment parent not found" for some connections, who are all on the same hub. Then I checked the delivery report for the original post, and it said for those same users "storage failed: unable to retrieve." I clicked on "redeliver" yesterday, and it said the same thing, so now the same status is listed twice for each account, on Wednesday, 17:50 and on Thursday 10:58. The next post I wrote, also on Wednesday about three hours later, was delivered to this particular hub.

Now my question, is this a problem on my hub or on the receiving hub? Is there something I or the remote admin can do about it?

FIRST: THANK YOU for providing a good and detailed report! As a side note - I'm glad to know that people are using the "deliverynotice" addon and are actually finding it helpful!

The messages you are seeing indicate that the remote hub is for some reason unable to obtain a copy of the parent message from your hub. If there are other remotes that are not having this problem, it is unlikely to be a problem on your hub.(though not impossible). My initial guess would be a possible DNS issue where the remote can't find your instance - it could also, possibly, be an older version of Hubzilla - or possibly a problem with an underlying library (eg, CURL) used by Hubzilla (a workaround for the CURL problem was applied somewhat recently in the 3.8.x stream somewhere). Those are my 3 top theories based on your description.

Specific remediation steps will depend on what the problem is and lots of specifics about the remote hub's installation.

I'm also on 3.8.8. Maybe it was just a one-time glitch, since everything I posted after got delivered. Unless it happens again, I'm just gonna ignore this. If it does happen again, I'll report back here.

@Mario Vavti I don't think so, there isn't anything left for hub.netzgemeinde.eu.

Also, I just found another, older one that I didn't notice before. @Mark Nowiasz Did my Happy New Year post with the video make it? For some reason, I can't call up a delivery report for the parent post (not available under the gear icon on that particular post), but there's another comment of mine underneath with the yellow line above it, and that also says "comment parent not found" for my contacts on your hub. The reason I didn't notice before is that the report starts with about 20 lines of "recipient not found", all with the same string (in place of a user name or location), so I didn't scroll down far enough before. But underneath that, it looks like this:This is for every connection on your hub, and it goes on all the way through January 5th, after which it presumably stopped trying.

@Mark Nowiasz Good thinking, but no. The New Year's video is public, visible even for not logged-in users (otherwise, no sharing to my diaspora contacts), and in the one from Wednesday I shared an article I wrote, which also has public permissions (although the post sharing it was private.)

This is the real problem. A post was delivered and accepted and was stored in the database. *Immediately* after storing it in the database it was fetched - and it wasn't there. If all posts are failing this might indicate a code problem or database server upgrade issue, but if it is only "random" posts which fail it is more likely that the database server is having some issues with resources (number of processes, locks or something like that).
